I remember software in the 90s having limits on how many computers you could use an application on (however rarely enforced)
I remember software in the '90s having "limited licenses," but operating on the honor system. Because you could just install it on as many computers as you wanted and there wasn't really a way for companies to stop you.
It wasn't until the early 2000s when I started seeing licenses verified through the Internet and actually limiting their usage.
